In step 2, the vehicle's power output and accessory energy consumption are adaptively adjusted based on the vehicle's real-time power level during a normal driving phase, including:

[0103] Obtaining the ambient temperature during normal driving, and prioritizing energy allocation to the vehicle's battery when the ambient temperature is below a preset threshold, and preheating the battery based on the allocation result;

[0104] The vehicle is divided into driving stages based on the preheating results. At the same time, the vehicle's driving section characteristics are retrieved from the historical database. Based on the driving section characteristics, the vehicle's power output in different driving stages is divided into steps to obtain a power output parameter reference table;

[0114] In this embodiment, the driving section feature refers to the type of road that the vehicle frequently drives on, such as an urban road or a bumpy rural road.

[0115] In this embodiment, the power output of the vehicle in different driving stages is divided into steps based on the characteristics of the driving section, which means that the power output of the vehicle in the starting, constant speed driving and deceleration stages is divided according to different road types, thereby facilitating the control of the power of the vehicle in different stages to achieve the purpose of energy saving.

[0116] In this embodiment, the road environment feature refers to the environment type of the road where the vehicle is currently located, for example, the flatness and width of the road.

The purpose is to adjust the power output of the vehicle to ensure normal driving of the vehicle.

[0130] In this embodiment, the energy recovery process refers to a solution for recovering excess energy of the vehicle during braking. For example, when the vehicle decelerates from a high speed to a low speed, the energy is recovered during the rapid deceleration process.

[0136] Log in to the vehicle's backend management terminal and adjust the parameters of the vehicle's standard operating procedures in the backend management terminal based on safe driving power;

[0137] Based on the parameter adjustment results, the system guides users to perform emergency driving. At the same time, it monitors the vehicle's battery status and soft-shuts down all vehicle components when the battery level reaches 0.

[0138] The vehicle is prohibited from driving based on the soft shutdown result, and the vehicle battery is protected from over-discharge based on the prohibition of driving.

[0139] In this embodiment, the emergency driving response mechanism is associated with the real-time power level of the vehicle, that is, when the vehicle power level enters the emergency driving phase interval, the emergency driving response mechanism is automatically activated to control the vehicle output power.

[0140] In this embodiment, the preset vehicle driving standard is set in advance and is used to represent the driving power required when the vehicle is low on battery power and can drive safely.

[0141] In this embodiment, guiding the user to perform emergency driving based on the parameter adjustment result means that after the parameter adjustment is performed, a guidance display is displayed on the vehicle's onboard display screen, including the force application interval of the accelerator pedal, etc.

[0142] In this embodiment, soft shutdown means that when the vehicle battery power reaches 0, the vehicle speed is slowly reduced to 0 and then the various components of the vehicle are locked in order to prevent over-discharge.

[0143] The beneficial effects of the above technical solution are: by determining the safe driving power of the vehicle within the emergency driving stage, the parameters of the vehicle standard operating procedures are adjusted according to the safe driving power, thereby ensuring that the vehicle can drive safely during the emergency driving stage. At the same time, when the vehicle power is 0, the various components of the vehicle are soft-shut down and driving control is prohibited, which protects the vehicle's battery and avoids over-discharge of the battery.

[0151] In this embodiment, the guidance scheme refers to a scheme for guiding the user's driving behavior, such as reminding the user to accelerate slowly during acceleration.

[0152] The beneficial effects of the above technical solution are: by analyzing the user's driving behavior habits, the user's energy waste points are determined, and the energy waste points are further analyzed to determine the guidance plan for the user's operating behavior.
